New leaves turning yellow under led
torgul2000started grow question 3y ago
My autos are turning into flowering. It seem I’m under led, respecting the grow schedule and new leaves are turning light green… is it normal or a deficiency/excess (iron?) ?
Thank you for the answers

This is absolutely normal.. all new growth is that light green and it will darken up to "normal" as it gets older... no worries!

Leaves fading and dying, started from bottom but spreadingI’m starting to be at a loss with this. Calmag issues earlier in veg, seemed to improve for a while but now bottom leaves started to die - I thought this was just due to beginning of flower but it’s getting worse and spreading even to healthier new growth. PH (should be) fine.5y ago

Should I cut the dried leaves at the bottom?Should I remove the dried leaf in the bottom? I was thinking that it might redirect unnecessary energy to the plant since the leaf might be too far gone to save. I was thinking of starting topping next week as well, when the fifth node start to show more.5y ago

Seedlings with yellowing leaf edgesAny insight on what may be causing the yellow edges on these seedlings?
I'm reusing FF Ocean Forest that I used on my last grow. I didn't amend the soil in these containers as I didn't expect they'd need anything before it was time to transplant. pH was good at last harvest.Week 2

Younger leafs are discolering. What to do?This week my WW started getting pale? I tried to look on examples on the net of discoloring leafs. Is this a Zinc defecienty? She seems to be struggeling a bit because of the colder nights. Could this also be due to that? Looking forwards to your answer, dear question replier!Week 7
